[0025] Example

[0026] Reference Figure 1-Figure 5 The utility model provides a technical solution: a protective device for a water pump, comprising a water pump body 1 and a protective mechanism 3. The bottom of the water pump body 1 is fixedly connected to the water inlet pipe 2. The protective mechanism 3 comprises a circular plate 31. The circular plate 31 is fixedly mounted on the outer surface of the water pump body 1. A groove is provided on the side of the circular plate 31. A rectangular plate 32 is rotatably mounted inside the groove. A floating block 33 is fixedly mounted on the bottom of the rectangular plate 32.

[0027] In a preferred embodiment, the top of the water pump body 1 is fixedly connected to a disc 4, the top of the disc 4 is fixedly connected to a handle 5, and the water outlet end of the water pump body 1 is fixedly connected to a water outlet pipe 6. For the convenience of use, the present device is provided with a disc 4 on the top of the water pump body 1, and a handle 5 is fixedly installed on the top of the disc 4. The handle 5 is lifted during use for easy carrying, and it is also convenient to take the water pump body 1 out of the water for easy operation.

[0028] In a preferred embodiment, the bottom of the water pump body 1 is fixedly connected to the mounting bracket 7, and a circular hole is provided on one side of the mounting bracket 7. The inside of the circular hole is fixedly connected to a filter screen cartridge 8. One end of the filter screen cartridge 8 is arranged inside the water inlet pipe 2, and the water is pumped through the water pump body 1 placed in the water. However, at present, the water pump body 1 is mostly placed in outdoor river water, and there are a lot of weeds in the river water. In order to prevent the weeds from being sucked into the water pump body 1 and causing damage, a filter screen cartridge 8 is installed at the position of the water inlet pipe 2. The water is filtered by the filter screen cartridge 8, which effectively prevents the weeds from being sucked into the water pump body 1, thereby ensuring that the water pump body 1 can be used normally.

[0029] In a preferred embodiment, the outer surface of the water pump body 1 is fixedly connected to the annular cylinder 9, and a slide groove 10 is provided on the outer surface of the annular cylinder 9. A slider 11 is provided inside the slide groove 10, and one side of the slider 11 is fixedly connected to the protective plate 12. When the device is not in use, it will be placed in the car. During the carrying process, it is inevitable to encounter bumpy roads, causing the water pump body 1 to roll in the car and collide with the inner wall of the car. In order to avoid damage to the water pump body 1, a limiting mechanism 13 is installed at one end of the rectangular plate 32. The limiting mechanism 13 includes a limiting plate 131, a plug hole 132 and a spring 133. A rectangular hole 14 is provided on one side of the rectangular plate 32. The interior of the rectangular hole 14 is fixedly connected to the spring 133. One end of the spring 133 is fixedly connected to the limiting plate 131, and the limiting plate 131 is slidably connected to the rectangular hole 1 4, a plug-in hole 132 is opened on the outer surface of the protective plate 12, and the position of the plug-in hole 132 corresponds to the position of the limit plate 131. The outer surface of the limit plate 131 is fixedly connected to the partition bar 15, and the mounting bracket 7 is set to a circular shape. The mounting bracket 7 is fixedly connected to the inner side of the annular cylinder 9. In actual use, by providing a plug-in hole 132 on the upper surface of the protective plate 12, one end of the rectangular plate 32 is internally slidably connected to the limit plate 131, and one side of the limit plate 131 is fixedly connected to the spring 133. The limit plate 131 is inserted into the inside of the plug-in hole 132, and under the action of the partition bar 15, the limit plate 131 is stably squeezed against the protective plate 12, so that the rectangular plate 32 moves to the side of the water pump body 1 to protect the water pump body 1 and avoid damage to the shell caused by collision, which meets the use requirements.

[0030] Specifically, the working process or working principle of a protective device for a water pump is as follows: currently, when using a water pump, the water pump is placed in water and connected to a power supply to make the water pump work in the water. Since the water pump itself has a certain weight, when placed in water, the water pump will be completely immersed in water, and there are wires connected to the water pump. When the water pump is used in the above manner for a long time, circuit problems are likely to occur, thereby causing damage to the water pump. Therefore, this device is designed to solve this problem. When using this device, the rectangular plate 32 is first unfolded so that the upper surface of the rectangular plate 32 is flush with the upper surface of the circular plate 31. The rectangular plate 32 and the circular plate 31 of this device are set to damped rotation, so that after the rectangular plate 32 is unfolded, the rectangular plate 32 will maintain a state and will not rotate at will. Then the water pump body 1 is placed in water. At this time, the rectangular plate 32 will float on the water surface under the action of the floating block 33. At this time, the water pump body 1 can be placed vertically in the water so that the water pump body 1 can be used stably.

[0031] The water pump body 1 is placed vertically in water, and the water inlet pipe 2 of the water pump body 1 is in the water, while the connection wires on the water pump body 1 are located outside the water surface, effectively avoiding circuit problems caused by water. Then, an external power supply is connected, and by turning on the water pump body 1, water can be pumped out through the water pump body 1 and transported to other locations through the water outlet pipe 6 to meet usage needs.

[0032] After the use of the device is finished, the water pump body 1 is fished out of the water. In order to save space and facilitate carrying, after the water pump body 1 is taken out, the protective plate 12 on the outside of the annular cylinder 9 can be slid to the position of the bottom end of the annular cylinder 9, and then the rectangular plate 32 is rotated and folded. At this time, the limiting plate 131 can be stored and squeezed into the inside of the rectangular hole 14. When the limiting plate 131 moves to the position corresponding to the plug hole 132, the limiting plate 131 can be loosened. At this time, the limiting plate Under the action of the spring 133, 131 will move the limit plate 131 into the interior of the plug-in hole 132. At the same time, under the limitation of the partition bar 15, the limit plate 131 will not fully extend into the interior of the plug-in hole 132, and the protective plate 12 will be squeezed by the partition bar 15 to stabilize the protective plate 12 at the bottom end of the annular cylinder 9. In this way, the rectangular plate 32 can protect the outside of the water pump body 1 to avoid bumps on the water pump body 1 during transportation, thereby ensuring that the water pump body 1 can be used normally and protected from damage.

[0033] It should be noted that the water pump body 1 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art. Its power supply, specific composition and principles are clear to those skilled in the art, so they are not described in detail.
